Short-lasting, sharp pain in the testicle that comes for a few minutes and then completely settles on its own is most often due to temporary and benign causes. When there is no fever, no swelling, no redness, and no continuous pain, serious conditions are unlikely. Such pain can occur due to transient muscle spasm around the testicle, mild nerve irritation, or referred discomfort from the urinary tract, especially just after passing urine. It can also happen with mild congestion of the epididymis, dehydration, straining during urination, sudden movements, or posture-related strain.
The fact that the pain lasted only a few minutes, resolved on its own, and appeared on different sides on different days is reassuring. This pattern does not suggest testicular torsion, infection, or any dangerous condition. Nasal congestion and a running nose are not directly related to testicular pain, but during minor viral illnesses the body can become more sensitive, which may trigger brief muscle or nerve-related discomfort.
Health Tips
For now, reassurance, good hydration, avoiding straining while passing urine, and wearing supportive underwear are usually sufficient. Medical evaluation is needed only if the pain becomes severe or persistent, if there is swelling, redness, warmth of the testicle, fever, vomiting, or if the pain lasts longer than one to two hours. Based on the history provided, this appears to be a self-limiting and non-serious issue.
Good luck!
